Got my PNY 275 yesterday. Using EVGA precision right now to monitor and OC. Currently it seems that about 675 core/1180 is all it will give me as far as overclocking goes with the side panel off my case.

With the panel on, See sig.

Is the vantage score in my sig about right for what this card should do given my system configuration?

During games, the temps stick to around 70~75*c with the fan manually set at 75%. Setting it to 100% doesn't lower the temps at all. It just takes a little longer to get there.
